HARRY WHITE, OF ONEIDA CASTLE, NEW YORK.

IMPROVEMENT IN SHINGLE-MACHINES.

Specification forming part of Letters Patent No. 56,64 dated July 24,1866.

To all whom it may concern:

Be 4it known that I, HARRY WHITE, of Oneida Castle, Oneida county, Stateof New York, have invented certain new and useful Improvements inShingle-Machines; and I do hereby declare the following description andaccompanying drawings are sufficient to enable any person skilled in theart or science to which it most nearly appertains to make and use mysaid invention or improvements without further invention or experiment.

The nature ofmy invention and improvements consists in certainimprovements on the shingle-machine patented to me on the 27th day ofMay, 1856, No. 14,977, by which improvements I have remedied the defectsin the machine then patented and perfected it.

These improvements may be enumerated as follows: in providing anautomatic feedingplate, to feed the blocks to be shaved just at theproper time' when they are required and in a forked spring-guidearranged to guide the upper ends of the blocks as they are fed into themachine into the proper position to be properly shaved on both sides;and in providing the clamping-plates with arms and adjusting-screws tosteady and support them when the machine is in operation 5 also, incertain devices for springing and holding the shaving-knives, so as toshave the shingle as thick eight or ten inches from the butt as it isshaved at the butt.

In the accompanying drawings, Figure l is an elevation of my machine forshaving shingles. Fig. 2 is a plan or top view; Fig. 3, an elevation ofone end. Fig. 4 is the forked rod, and Fig. 5 the connecting-link.

In these drawings, A A are top and bottom frames, made of cast-iron orother material in the form shown, or in such other form as will answerthe purpose. These frames are connected by the bars B B B, which holdthem a proper distance apart horizontally, as shown in Fig. l. On theunder side of the main bar of the top frame, A, there are two ways orrails, C, and the same on the upper side of the frame A'. Between theserails C C perpendicularly the carriage is fitted to traversehorizontally, which consists of two frames, D D, with grooved edges to tthe ways, which frames are connected by the bolt E, which gin to cut atone' corner of the shingle at the thick end, and finish cutting at theopposite corner diagonally at the thin end, ofthe shin gle, so as toshave them smooth. These knives H are fastened to the carriage D andadjusted by the screws I. The screw K passes through the frame andthrough the knife H, to draw the middle of the knife toward the frameand curve it to shave the shingles and leave them as thick one-third orone-half the way from the butt toward the point as they are at the butt.

The screw above the screw' K is screwed against the knife to prevent itfrom springing and hold it firmly. The pieces J are fastened to thelower bars of the frames D by screws L L, to adjust them at an angle toeach other and form a trough to receive the ends of the blocks to beshaved, and the inclination of the pieces J brings the end of the blockin the center between them.

VTo hold the shingle or block in the proper position and carry one edgeto the bar G, there are two pieces like N, with their lower endsfastened to the lower part of the carriage, so that the upper ends willswing out between the pins M M when they pass onto the wedges P,fastened to the sides of the frame A.

The horizontal clamping-plates Q, are fastened to the pieces or leversN, and are pressed against the block by the springs S S, fastened to thelower bar of the carriage, as the ends of the levers N pass off of thewedges P, so as to clamp the block in the center of the carriage andcarry it against the bar G to be shaved. The arms R R are fastenedfirmly to the plates Q, Q, and extend up onto the upper bar of theframes D, with set-screws in their upper ends, to stop theclamping-plates Q a proper distance each side of the center, and so thatthey will pass back by the bar Gr after the shingle is shaved withouttouching the bar.

The plates T T are fastened on the top of frame A to form ways for thefeeding-plate V to traverse between. This plate V covers thefeeding-hole W, and holds up the block which is placed upon it yuntilthe carriage runs back and carries the wedge U (shown in dotted lines inFig. 2) under the lug X on the feeding-plate, which is moved back anddrawn from under the block, which drops into the carriage with its lowerend between the pieces J, and as the wedge U is fastened to the upperend of the lever N, when the carriage is run forward the wedge is moved,and the feeding-plate V is drawn over the hole W by the springs Y Y,(shown by dotted lines in Fig. 2,) under the arms V of the plate V,which arms Vl have their outer ends turned down and perforated totraverse on the pins in the frame A, around which pins the springs Y areplaced.

To hold the blocks perpendicular over the feeding-hole W, the plates Tare perforated for the stands a a, (shown by dotted lines in Fig. 1,) towhich stands the board Z is fastened so as to stand perpendicularlybeside the feeding-hole, and the cleat b on the board at the end of thefeeding-hole; and to hold the block upright by the side of the board Z aplate of sheet metal, Z', is fastened to the board and bent over andturned down, so as to stand off from the board far enough for the upperend of the block placed on the feeding-plate to stand between the plateand the board when placed there by the attendant to feed the machine.

To guide the upper end of the block to the bar G the rod c is arrangedto traverse in the stands d d under the frame A. This rod c is made inthe form shown in Fig. with a forked end to pass each side of the bar G,and the ends of the prongs are made aring to receive the edge of theblock and guide it centrally against the bar G, the rod being pushedback by the block against the spring c, and to move the end of the rodout of the way of the knives the long nut f is put upon it, so that whenthe carriage runs forward it strikes the nut f and moves the ends of therod out ot the way of the knives.

The clamping-plates g g are arranged behind knives to seize the shingleafter it is shaved. These plates are held and pressed together by thesprings h h fastened to the frames D, and they carry the shingle out ofthe machine when they are spread by the post j to let the shingle drop.

The machine having been constructed as described and power applied totraverse the carriage, the attendant places a block on the feeding-plate(V) side of the board Z, with its upper end behind the plate Z', and asthe carriage is run back the Wedge U draws the plate V from under theblock. and it drops through the feeding-hole W with its lower endbetween the plates N, and when the carriage moves forward theclamping-plates Q close upon the block and carry it against the bar G,the rod c receiving and guiding the upper corner. TheI plates Q slipoft' of the block as it is shaved, and the plates g behind the knivesseize the shingle and carry it out of the machine and let it drop at thesame time that a block is dropped through the feeding-hole W, and theoperation is repeated.

Having described my improvements, I claim- 1. The combination andarrangement of the automatic feeding-plate V, the forked guiderod c, andthe adjusting-arms R R, the whole being arranged for joint operationsubstantially as described.

2. Adjusting the knives to shave the shingles in the form described bythe means substantially as described.
